Efficient converter for hot water of 90 degrees C into 3 kilowatts (100 V, 30 A) of electricity.
With the world facing global warming and an ever reducing supply of oil resources, there is a clear and present need for new technology research in renewable energy. Furthermore, in light of the recent great east Japan earthquake, the shutdown of thermal and nuclear based power plants has created brand new demands not only for energy efficient technologies, but also for the immediate utilization of brand new, yet untapped alternative sources of energy. Once such source, underutilized but in abundance, is low temperature heat source below 150 degrees C, which commonly exists in the form of waste heat from factories, solar heat, or hot springs. Modern attempts to utilize such heat sources are limited in scale to the 50+ kilowatt range, and only to sites able to meet restrictive requirements such as high volume heat, large space, expensive upfront costs.

What does a cup of water equate to, these days? During summers, a cup of water could barely quench my thirst. However, with a new technology developed by Leeds University, a cup of water could mean a kilogram of laundry. Xeros, a Leeds University spin-off, is currently commercializing a washing machine which can clean clothes using just a cup of water.
According to a study by Waterwise (a UK NGO), the water used to wash clothes in the UK alone amounts to 145 Olympic size swimming pools daily. The Xeros washing machine only uses 2 percent of the water as well as the energy used by its conventional counterparts. And, since the machine only uses a cup of water per kilogram of laundry, the clothes come up almost dry, eliminating the necessity to tumble dry. The company has already received a $1 million funding and expect to put washing machines out in the market by 2009 at the earliest.
